Another clunk, this time in the rear

[Karmann]

Let's play another installment of the "guess that noise game." This week's contestant is me, and when I go over larger bumps on the passenger side of the car, there is a mezzo-forte (medium loud) "THUNK" noise that occurs from the rear end. I don't feel it in the steering etc but it's definitely audible. I've gone through my trunk, and nothing makes that noise there. It just started making the noise after my trip to Joshua Tree NP, and some washboard experience probably aggravated it.

 

I crawled under the truck this morning, and looked at all the bushings. They all seem to be in tact, but my upper trailing arms noticeably wiggle when rocked back and forth, especially the passenger side one. Is this normal? Their bushings appear to be in tact as well, but maybe not?

 

Thanks

I think you've answered your own question brother.

my only suggestion is to go through all the bolts involved in your recent suspension upgrade and re-torque everything!
